Embodiment 1

[0050] figure 1 is a top view of the display device of this embodiment, and figure 2 for along figure 1 A schematic sectional view of the section line L1-L2 shown. The display device of this embodiment includes: a display panel 11 ; an upper polarizer 12 disposed on one side of the display panel 11 ; and a lower polarizer 13 disposed on the other side of the display panel 11 . In addition, the display panel in this embodiment is a liquid crystal display panel, so the display device in this embodiment further includes a backlight module 14 disposed under the lower polarizer 13 . The aforementioned display panel 11, upper polarizer 12, lower polarizer 13 and backlight module 14 are all arranged in a frame 15, and the space between the upper polarizer 12, the lower polarizer 13 and the frame 15 can be selectively filled with a colloid 16.

Embodiment 2

[0065] Figure 5 It is a schematic cross-sectional view of a part of the display device of this embodiment. The display device of this embodiment is similar in structure to the display device of Embodiment 1 except for the following differences.

[0066] The display device in Embodiment 1 is a liquid crystal display device, and the display device in this embodiment is an OLED display device. Therefore, see figure 2 , in the display device of the present embodiment, the backlight module 14 and the lower polarizer 13 of the first embodiment may not be provided.

[0067] In addition, if Figure 5 As shown, in this embodiment, the upper polarizer 12 can be directly arranged on the display medium layer 112 of the display panel 11, that is, the display panel 11 of this embodiment does not include Figure 3A The opposite side substrate 113 is shown. However, the present invention is not limited thereto; in other embodiments of the OLED display device of the present invention, t...

Embodiment 3

[0069] Figure 6 is a partial cross-sectional schematic diagram of the display device of this embodiment; and Figure 7 It is a top view of the upper polarizer disposed on the display panel of this embodiment. The display device of this embodiment is similar in structure to the display device of Embodiment 1 except for the following differences.

[0070] Such as Figure 3A As shown, each film layer of the upper polarizer 12 in the first embodiment is designed to be tapered upwards from the display panel 11 . Such as Figure 6 As shown, each film layer of the upper polarizer 12 in this embodiment is designed to gradually increase from the display panel 11 upward. However, whether it is Figure 3A Each film layer is the upper polarizer 12 with tapered design or such as Figure 6 Each layer of the upper polarizer 12 is designed to be gradually larger, and the upper polarizer 12 has an uneven edge design, which can increase the contact area between the colloid 16 and the upper...

Abstract

The present invention provides a display device, comprising: a substrate; a display medium layer disposed on the substrate; a polarizer disposed on the display medium layer, the polarizer comprising a first film layer, a second film layer stacked in sequence film layer and a third film layer, the first film layer is connected to the second film layer, the second film layer is connected to the third film layer, a first lower surface of the first film layer has a first edge, and the second film layer A second lower surface of the layer has a second edge, and a third lower surface of the third film layer has a third edge; wherein, in a first direction parallel to the substrate, the first edge and the second edge are at A first shortest distance of the projection of the substrate in the first direction is not equal to a second shortest distance of the projections of the second edge and the third edge on the substrate in the first direction.

Description

technical field [0001] The present invention relates to a display device, and more particularly to a display device using polarizers with non-flush edges. Background technique [0002] With the continuous advancement of display technology, all display panels are developing toward small size, thin thickness, and light weight. Therefore, the current mainstream display devices on the market have developed from the previous cathode ray tubes to thin displays, such as liquid crystal display panels, An organic light emitting diode display panel or an inorganic light emitting diode display panel, etc. Among them, thin displays can be applied in quite a lot of fields. For example, most of the display panels used in daily life such as mobile phones, notebook computers, video cameras, cameras, music players, mobile navigation devices, and televisions use these display panels. [0003] Although liquid crystal display devices or organic light-emitting diode display devices have become ...
